Freon™ MO99 (R-438A) Refrigerant

Freon™ MO99 is the newest addition to the Freon™ family of refrigerants. Freon™ MO99 is the most versatile refrigerant for replacing R-22 in direct expansion (DX) air conditioning and refrigeration systems. It provides benefits in commercial and residential air conditioning, in medium and low-temperature commercial refrigeration and DX water chiller systems with positive displacement compressors.

Lubricant Recommendation Freon™ MO99 is compatible with traditional and new lubricants, including mineral oil, alkylbenzene and polyol ester. In most cases, no change of lubricant type during retrofit is needed. Refer to retrofit guidelines for additional information.
